Smartwatches are wearable computer devices that are designed to be worn on the wrist. They offer many of the same features and functions as smartphones, but in a smaller, more convenient form factor. They often connect to a user’s smartphone, allowing them to receive notifications, make Phone calls, send messages, and access apps and other features without having to take out their phone. One of the key features of Smartwatches is the ability to track health and fitness data.
